    摘要： An exhaust gas treatment system for an internal combustion engine is provided and includes an exhaust gas conduit, a hydrocarbon supply, a particulate filter (“PF”), at least one sensor, a first temperature sensor, a second temperature sensor, and a control module. The PF is in fluid communication with the exhaust gas conduit and has a filter structure for removal of particulates in the exhaust gas. The filter structure has an innermost region and an outermost region. The PF is selectively regenerated during operation of the internal combustion engine. The PF has a stratified temperature structure that causes the particulates trapped at the innermost region of the PF burn off before the particulates trapped in the outermost region of the PF during regeneration. The control module has a memory with an infinite stage temperature control curve stored thereon.

    摘要： An engine control system includes an injection determination module, a correction factor determination module, and a regeneration control module. The injection determination module determines a desired amount of hydrocarbons (HC) to inject into exhaust gas produced by an engine based a flow rate of the exhaust gas. The correction factor determination module determines a correction factor for the desired amount of HC based on engine speed and engine load. The regeneration control module controls injection of an adjusted amount of HC into the exhaust gas during regeneration of a particulate matter filter, wherein the adjusted amount of HC is based on the desired amount of HC and the correction factor.

The method further includes removing the restriction to the air intake throttle when the engine is operating in the air restriction mode, one of a change in position of the accelerator pedal over a period of time is greater than a pre-defined pedal acceleration rate or the position of the accelerator pedal is equal to a pre-defined pedal limit, and the speed of the vehicle is less than a pre-defined speed limit.

    摘要： A temperature of exhaust gas downstream of an oxidation catalyst is compared to a temperature of the exhaust gas upstream of the oxidation catalyst to determine if the downstream temperature is increasing over time or decreasing over time as hydrocarbons are injected into the flow of exhaust gas to regenerate a particulate filter. The oxidation catalyst is determined to be quenched when the temperature of the exhaust gas downstream of the oxidation catalyst remains constant or decreases over time as the rate at which the hydrocarbons are injected into the exhaust gas increases. The oxidation catalyst is determined to not be quenched when the temperature of the exhaust gas downstream of the oxidation catalyst increases over time as the rate at which the hydrocarbons are injected into the exhaust gas increases.
